yes crystal is really awesome

@sdogruyol
@krypton97 indeed :100:
unreadable
@unreadable
wondering id there's something similar with try/catch block in crystal o.O
Ghost
@ghost~55586c4815522ed4b3e08557
yep: begin/rescure/ensure (doc: https://crystal-lang.org/docs/syntax_and_semantics/exception_handling.html)
unreadable
@unreadable
Yeah, I've found that
gonna play with it
rn
unreadable
@unreadable
begin/rescue/else works like a charm
Well done crystal team. No more err != nil bs..
Serdar Dogruyol - Sedo セド
@sdogruyol
Oh, what do you mean?
unreadable
@unreadable
err != nil is specific to Golang. Go libraries are written that way so they always return an error (nil or something else)
Serdar Dogruyol - Sedo セド
@sdogruyol
Ahh, now i get it
I don't like that kind of error handling
unreadable
@unreadable
It's a pain..doing assertion for every function it's not productive at all

Hi, i'm new to crystal any crud sample with sqlite or any rdbms ?
unreadable
@unreadable
https://github.com/crystal-lang/crystal-sqlite3
It has some nice samples
cevarief
@cevarief
@krypton97 Thank you.

@unreadable
If you need any help I'm here. Currently working with sqlite as well

<jokke> hey
Serdar Dogruyol - Sedo セド
@sdogruyol
hey @jokke
From IRC (bridge bot)
@FromIRC
<jokke> if i were to develop an alternative stdlib, how would i provide a prelude file for it?
<jokke> i tried putting a file "prelude.cr" in src/<project_name>/
Serdar Dogruyol - Sedo セド
@sdogruyol
can't you do that with --prelude ?
From IRC (bridge bot)
@FromIRC
<jokke> and then compiling something with --prelude prelude
<jokke> but that just seems to include the standard prelude
<jokke> at least it let me use puts, which isn't in my stdlib
Ghost
@ghost~55586c4815522ed4b3e08557
you need --prelude "./prelude"
Serdar Dogruyol - Sedo セド
@sdogruyol
seems like so https://github.com/crystal-lang/crystal/blob/ffb748fc182d61222bc780d6dfa9605ce3351b63/src/compiler/crystal/command.cr#L368
From IRC (bridge bot)
@FromIRC
<jokke> @bew: and what if i want to build another project which uses my stdlib as a dep?
Ghost
@ghost~55586c4815522ed4b3e08557
it uses the same "path" logic than require iirc
From IRC (bridge bot)
@FromIRC
<jokke> @bew: ah i see
<jokke> okay, so then it would be <my_lib>/prelude
<jokke> thanks :⁠)
Ghost
@ghost~55586c4815522ed4b3e08557
yes should be ;)
From IRC (bridge bot)
@FromIRC
<jokke> are there any gc libs in crystal in the works?
Serdar Dogruyol - Sedo セド
@sdogruyol
nope
From IRC (bridge bot)
@FromIRC
<jokke> dang
Serdar Dogruyol - Sedo セド
@sdogruyol
I'm not aware of any GC written in Crystal
we need one though but not now :P
From IRC (bridge bot)
@FromIRC
<jokke> :⁠)
<jokke> i was pretty impressed when i found out that go has zero C deps
Serdar Dogruyol - Sedo セド
@sdogruyol
writing a GC is tough, not the GC itself though :D
yeah, they've written everything in Go but that took like 3-4 years
From IRC (bridge bot)
@FromIRC
<jokke> yeah
<jokke> even the cryptostuff
<jokke> but i hate go :⁠D
<jokke> i think it's a terrible language
Serdar Dogruyol - Sedo セド
@sdogruyol
heck, they even have image manipulation in go
From IRC (bridge bot)
@FromIRC
<Papierkorb> jokke: My pure crystal GC can't scan the stack yet, so not useful. Had to hack the stdlib a bit though
